Referring to the drawings, 1 designates the supporting frame; 2 the drive shaft of the machine, `and 3 an upper' transerse shaft on which is loosely mounted a pulley 4C that is connected with and continuously driven from a pulley 5 on the drive shaft by means of a belt G.

7 designates a third shaft which is intermittently and continuously rotated as will presently appear. llast on theshaft 7 are .spaced-apart'wheels t3, 8 to which are affixed appropriate segmental pattern cams 9 ythat determine the succeeding movements of the mechanism for controlling the various positions of the block-supporting table 10'in the usual manner.

11 designates a fourthv shaft which is driven from the shaft 2 by means of a belt 12 passing about pulleys 13,14 on the shafts 2, 11, respectively. On the sha' t lisis a pulley 15 which is operatively connected with the pulley 16 of the drill head by means of a belt 17 so as to continuously rotate the drill, which drill is mounted for vertical movement toward and from the path of the blocksupporting table. The periodical vertical movements of the drill in respect to the block (i3.) on the table l0, so as to bore tuftreceiving holes in thev block, is effected by means of a rock-lever 18 which is fulcrumed on the supporting frame, one of the arms of the lever being coupled to the movable drill support, and the other arm having a roll connection, as usual., with an appropriate cam 19 fast on the shaft 3. j

20 designates the magazine from which quantities of fibre, or bristles, are successively removed and fed into position for insertion, as tufts, into the holes of the adjacent bored block (B) on the table 10. The tuft inserting mechanism includes devices whereby each tuft is seated and fastened in a'hole in the block by means of a wire staple, which staple when driven toward and into the hole of the block straddles Ythe Wisp, doubles the wisp on itself, carries'the tuft thus formed into the hole, and securely fastens it therein.

On the lshaft 7 is a` relatively large gear wheel 21 with which meshes a smaller gear wheel 22 carried by a shaft 23 journaled in suitable bearings on the main frame. Thel shaft 23 bears a ratchet wheel 24 the teeth of which are engaged by a pawl 25 on one arm of a crank lever 26 that is fulcrumed on the shaft 23. The other arm of the lever is connected by means of a link 27 with one arm of a crank lever 28 that is fulcrumed on the frame adjacent the shaft 8. The other arm of the latter lever is provided with a roll 29 that runs on an appropriate cam 30 that is mounted on the shaft 3. Means, including manually operable devices, are provided whereby the cam can be coupled Vat will to the continuously driven pulley l so as to turn therewith, and including, also, devices whereby the cam is automatically released at prcdermined intervals, as will hereinafterv nection with the pulley l the lever 28 is actuated in a manner to oscillate the pawl bearing lever 26 and effect by its pawl the uniform .intermittent rotation of the associated ratchet and gear wheels, Vwhich motion is transmitted to the gear wheel 21 and, perforce, to the shaft. 7 and its pattern cani wheels. n

In the present instance the cam 30 comn prises an eccentric disk formed with an elongated sleeve or hub 32 which loosely encircles the shaft 8. This sleeve is provided at lthe end adjacent the pulley Ll, with a brake drum 33 upon one face of which is pivoted a clutch lever 34, the shorter arm whereof terminates in a head 35 that, by actuation of the lever, is movable into and 'rom the path of a laterally projecting stud 36 on the pulley. `When the lever head is in the path of the stud, the latter bearsl against the head and thereby rotates the sleeve and cam concurrently with the pulley, but when the lever head is withdrawn from such path the pulley rotates idly andthe sleeve and cam are quiescent. The clutch lever is held normally in stud 'engaging position by the pressure against its longer arm of a spring;l 37 which is supported by a suitably-disposed stem 3S mounted on the side of the brake drum. The brake drum is embraced by a pair of pivoted brake members 39 terminatingin parallel jaws 4t() that are connected by a` spring-pressed rod /tl which tends to maintain the said nien'ibcrs in clamping rclation with the brake drum. -'l`hese inc-.nn bers are supported by an arm ft2 pivoted 'to a bracket 4.53 on an adjacent part of the main frame. (Sec Figs. G and 7.)

interposed between the brake javv's is a cam 4.41 fast. onv a roker-shaft d5 having its bearing in a bracket on the main frame. (in one end of this shaft is secured.A an arm 4G having at its free end a roll 47. which, when the shaft is properly actuated at. pred-eter mined periods by manually operative and automatic controlling niechanisms. such as hereina ter described, to release the brake members from the drum in one period and to apply them thereto in another period, is moved respectively out of and into the path of the longer arm of the lever 34: as the drum rotates. By the operation of the manual control the roll is lowered and, in -ffonsequence, th-e lever arm escapes the roll and is maintained in the path of the pulley stud llt) ioY

36 by the action of the spring 37; the brake at the same time being released to permit the free rotation of the cam element Awith the pulley. By the operation of the automatic control the roll is-i'aised into the path of the lever. arm and. inv consequence, such arm abuts against the roll and Vis thereby held` with its head beyond the path of the pulley stud; the brake at they sametime'being applied to the drum `to prevent the cam element from drifting beyond the proper stopping and starting point. The control mechanisms just referred to are of the following construction, reference being had to Figs. 2, 3, 4, 6, 7, 8 and 9 of the drawings.

Fast on the shaft is an arm @t8 to which and to the main frame are jointed the respective members of a toggle 49 which is `maintained in its straight or open position and against a suitably-disposed stop 50 on the frame, by means of a spring 5l secured to one of said members `and to the frame. Then the toggle is in this position the arm Li6 is maintained with its roll 41T in the path of the depending arm of the clutch lever 34 and the rocker-cam ffl in position with the brake applied. On the lowei' member of the toggle is a laterally projecting roll 52 against which Vbeai's anioscillatory cum lever 53 which is fast on a stud-shaft 5e journaled inV a suitable bearingin the frame. The longer arm of the lever 53 constitutes the cam member, and theshorter arm is connected by means of a link 540 with an arm 550 fast on one end of a rocker-shaft 560 having` its bearing in the bracket 570. The free end of the shaft 560 is equipped with a handle 580 which, when it is turned vto the right or to the left, turns the shaft and its arm in a manner to depress the linlrhfltl and swing' the cam arm of the lever 53 vforcibly up 'ard against the roll 52 of the toggle, thereby pushing the toggle outward vbeyond the vertical and against the action of the spring 5l, and perfoice drawing down the'ari'niS and partially turning' the rocker-shaft 45. Consequently the roll i7 of the arm e6 is removed from the path of the depending ,arm of the clutch lever 34, the head of the latter is causedto assume rits position in the spring 51, by means of a suitable lockingl device, which, in the present instance, com.- prises an arm 590 which 1s hung on the shaft Y' 5d laterally of the cam lever 53 and isformed VKwith anotched outer end portion 600` T he cam lever isgprovided with lower and upper lugs (310, 620 Ywhich respe'tively underlie and overhang the body of the locking arm,

the. relation of the parts being such thatv jecting stud 690 on the gear wheel. stud at a predetermined interval in the ro- Vcam 440 similar tothe rocker cam 44e.

when the cam lever' is being raised and the rthe upper lug 620 forces the locking arm downward and away from the lroll in a manner to release the teggle and permit the `spring 5l to return it to its straight position;'thus interrupting the connection be-V tween the pulley and the cam element, applying. the brake and stopping the rotation of the cam element. v

'Projecting from the shaft 54 is any arm 63,0 which is connected by means of a link G40 with a crank-'arm G50 fixed on a rockshaft 660 located laterally adjacent the gear wheel 2l. On this shaft is also` fixed an arm 670 provided with a camvhead 680 which lies normally in the path of a laterally pro- This tation ef the gear wheel impinges against the cam head Aand swings the rock shaft and the arm r650 in a mannerv to raise th-e link G40 and the arm (S30, thus loweringthe cam arm and causing the upperlugGQO to im` pinge against the locking arm 590A and yeffect the release of the toggle and for the purpose'previously eizplained. n

On the shaft 3, adjacent the cam 30, is secured a brake drum 330, on one side Vof vided with a tooth ldwhich by actuation of the lever is movable into and from engagement with a notch in a head B lifted outbe adjacent end of the cainhub or sleeve 32, and

the brake drum 330 is providedvwith bi'akemembers 390 which are operable by a rocker The shaft 450 of the cam '440 has its bearing in a bracket57l andis provided with anarm Li6() having at its outer vend a roll 470 which, coincidentally with the operation of the shaft to apply the brake members toy the drum S30, is movedinto position to actuate the clutch lever 340 and disengage its tooth from the notched head 360,

lVhen the clutch lever is engaged with the notched head, the motion is transmitted to Jthe shaft 3 and its iXed camsr from the cam sleeve 32, but when the lever is disengaged vfrom the head the motion of the shaft is'at once stopped. The rocker-shaft 450 is automaticallyoperated 4 at v predetermined inter# vals to engage and disengage the lever with and from the clutch head respectively. Accordingly the shaft is equipped with an ai'm 480 which is connected by means of arod 681 with one arm of a crank lever 691fu1- lit) normally in the path of a suitably disposed cam 700 on the gear wheel 2l by the action of the spring and cam connections of the brake. v A

The co-operative relation of the parts just described is such that when the cranlrlever 691 is in the normal position, the clutch lever` 340 is disengaged from the clutch head 360 and the brakel members 390 grip and hold the brake drum 330; but when such crank lever is engaged by the cam 700 the 1lever is moved against the force of the brake spring in a manner to effect a partial turn of the rocker-cam 440, thereby moving the Vroll 470 into the path of the clutch `lever 340 and effecting the engagement of the latter with the clutch head, and also coincidentally releasing the brake-members from the drum 330. a

On the shaft 3 are secured, in addition to the cam 19 which operates the boring devices, the cam elements for operating the fibre gathering and the tuft inserting and fastening mechanisms, and hence by virtue of the described mechanism'for automatically controlling the active and idle periods of the shaft, while the pattern wheels arein operation, there can be accomplished the automatic filling of a brush block in which the spaces between adjacent holes exceed the throw imparted to the bloc-lr by a single intermittent movement of the pattern wheels.

Y That is to say, if it be desired tofill two ends,

for example, of a brush block, leaving the Y center plain, the cam 700 on the gear wheel V2l is so formed and disposed as to effect the release of the clutch lever 340 from the clutch head and, coincidentally, apply the brake to the drum 330, for a predetermined interval during which the cam is continuously driven'fromthe pulley 4l until the block has been intermittently advanced a number of steps comprising its plain surface, and then to effect the re-engagement of the clutch lever 340 and the release of the associated brake preparatory to the resumption of the boring` and filling operations on the other end of the block. VUpon the completion. of the brush the clutch lever 34 and its associated brake are actuated through the stud 690 and connections hereinbefore described in a mannerto disconnect the cam 30 from the pulley l and apply the brake tov the drum 33; thus stopping the operation not only of the pattern mechanism but also of the boring and filling mechanisms. 'To resume the operation it 1s merely necessary to turn the handle '580 of the rockenshaft as previously explained.

It will also be seen thatV by the described control mechanisms the continuous boring and lling of more than one block at a time may be accomplished,y (by using a multiple table) since the cam 700 can be so formed and positioned as to render the shaft 3 and v its cams idle during` the time that the pattern mechanism which is under the influence of the active cam 30 is moving one bloclrfrom and another block into operating position Y the velocity of the shaft 7 and the pattern wheels, can be accelerated, during Such periods of the operating cycle that the boring 'and filling mechanisms are idle, thus increasing the output and efficiency of the machine, l provide automatic rapid speed mechanism of the following description, reference being had to Figures l, 2, 3, 4 and 5 of the drawings.

Journaled in suitably disposed bearings is a shaft 710 havinO` a tight pulley 720 which is connected with and driven from a tight pulley 730 on the shaft 2 by means of a belt 740. Adjacent the pulley 720 is ,pivotall'y supported the lower end of an upstanding Vrock frame 750 in the upper end' of which are mounted parallel shafts 760, 770 bearing meshing gear wheels 780, 790, respectively. Fast on the shaft 760 is a pulley 800 which is connected with and driven from a tight pulley 810 on the shaft 710 by means of a belt 820, and hence the motion is transmitted to the gear wheels 780,' 790. The latter wheel isso disposed that by actuation of the lrock frame, said wheel 790 may be moved into or out of mesh withl a gear wheel 830 tight on the shaft 23 thatvbears the gear 2 2 and ratchet wheel 24. vA spring 840 secured to the roclnframe and to the main frame tends to maintain the former positioned with the gear wheel 7 90 in mesh with the gear 830, and therefore the motion is transmitted through the Y gear 830 to the shaft 23 and thence through the gear 22V to thegear 2l,Vr

on the pattern wheel shaft 7. As the. movement thus imparted to the shaft 7 is continuous and at a higher speed than that trans mitted intermittently thereto through the ratchet wheel 24, the velocity of the shaft Z and its pattern wheels is accederated, thus the periodic l eo As a simple andefficient means whereby Y Al l0 l tension at 67..

Thereupon 'the shaft i is intermittently operated through the ratchet wheel as previously described,

until such time as thegear 790 is permitted to resume its engagement with the gear 830. rlhe gear 790 canV be thrown into or out of. operation at any `predetermined point or points or for :any desired period or periods "of the operating cycle, by the proper attachment ci one or more-cams, as 860, to the gear wheel Q1.

The

cal sha-'tt v54 suitably supported by the iframe;r spaced parallel side walls 55 borne bythe sides of said structure, and a back wall 56, whichV latter wall is affixed to brackets 57 that are adjustably secured in place by set screws 58 passing-through slots 59 in said sides as usual. The open bottom ot Vthe magazine overhangs an oscillatory libre gathering device by means ot' whichV quantities of libre aresuc'cessively separated from the mass vin the magazine and fed into position for insertion, as tufts, into the adjacent bored block (B) on the table l0.

rlhis device, in its preferred form, come,

nbre collected. The arm is provided at itsv ends with set-screws 63 which `extend through elongated slots inthe bar 60,-and serve to secure the arm in any predetermined position of vertical adjustment. l

The segmental fibre gathering bar60 is supported by the arms of a carrier 64 which is mounted tor oscillation lon the vertical shaft 5st. The carrier is connected Vby means or a rod 65 with one arm 66 of a bell-crank lever 'fulcrumed on a frame eX- shaiit 3; 4the contour of' the cam race being such as to eiiect through the leverand linkv connections variable backward and forward motions ofthe carrier and its fibre gathering .bar for a purpose hereinaiter described;-

Beneath the carrier is an arm which is` libre magazinerherein illustrated comprises a vertically-disposed U`structuife 53 projecting :from-and secured to a vert1'.

The other arm j of the l lever bears a roll 68 which runs in the race of an appropriate face cani 69 fast on the aim mounted to oscillate on the shaft 54e. This arm 70l extends outwardly under the segmental barandcarries'at its outer end la pair ot'spaced segmental-plates 7l,which are shaped to embrace the bar and extend to the top 'oit the latter.A The plates are ixed to the arml by screws 7 0', and are alsov slidably connected with `the. tutt bar by,v screws 7:25 passing through slot 7l in vthe bar. The y forward vor acting `ends of the "plates v71 are reduced and beveled to form clamping points, as 72, which, bythe relaf tive rotary movement of the plates and bar,r`

can be caused to'overhang. and recede from the wispf'of fibresupported in the gap, thus respectively clamping and releasing the libre. Fast onthe arm 70- is a depending blockv or projection 73, constituting a bumper, Vinto theY pathf of which vprojects two spaced apart stops 74, 75 .fast on an arcuate' frame extension 76 located below the carrier, whereby during ,the oscillation" of .the armV the bumper engages the stops1in` alternation.

clusive). v-

Mounted injg'uide brackets 77 onthe underside of the arm 7 0V is a radially-.movable (See Figs.' l and lOvto 13, in#

rbolt78 which is maintained normally provjected .outwardly by means of a suitablydisposedy spring 79 confined in one of the brackets.y The outer end of the bolt is Vf shaped,as at 80, and its inclined faces, en. gage one side or the otherA of a studk 8l thatl depends from the carrierthrough an arcuate s'lot 82 in the arm.l The bolt connection .is

such that during the forward stroke of the carrier thebolt is position'edto bear against the rear of the stud, and hence the arm is 'moved Yforward by and with the carrier until the bumper fimpinges against the opposingvstop 7d.` Thereupon the forward motion of the armis stopped and, in conse'- quence, as thefcarrier continues its stroke,

the spring bolt is forced inwardiand released from thevstud. In the return stroke of the carrier the bolt .impinges against the front of the stud and forces the arm rearward with the carrier until the bumper impinges against the rear stop. 75,v whereupon the rearward motion ot' the arm is stopped, and, as the stroke. oiy the' carrier continues, the bolt is forced inward and released from the stud.

` The contour of the race of cam 69 is'such that strokes of varying extent are imparted thereby through the connecting rod 65 to the oscillatory fibre carrier in such a mannerl as to give the gap of the bar several opportunities to be filled with vlibres yfrom the magazine; thatis to say, vthe carrier is first given a backward strokefrom the. tuft insertingstation until the gap of the tutt bar passes beneath the magazine and reaches the rearward wall ofthe latter; then the carrier is given a partial forward stroke to advance,-

the gap to the orwardwallof themagazine;

lOO

isov

' the tuft inserting station.

then the carrier is Vgiven a rearward Vstroke to move the gap beyond the rear wall of the magazine; then, finally, the carrier is given a full forward stroke to advance the gap to In each of the movements of the gap beneathy the magazine, excepting the final forward'movement, such gap is given an opportunity to be filled with fibre. In its final movement rearward of the magazine the bumper '73,.abutsagainst the stop and thus shifts the segment plates 7l in a. manner to advance the'points l72 thereof into clamping relation to the gap and thereby confine the contained wisp of fibre. vIn the next succeeding forward motion of the carrier beyond the magazine the bumper 73 impinges against the stop 74 which effects the opening of the clamping rpoints in a manner to release the fibre, at which juncture the fibre is located beneath the tuft inserting mechanism hereinafter described, and-is removed from the gap and supported by novel clamping devices. Such devices, in their preferred form, comprises a pair of parallel arms 83 secured to a support 84 on the main frame and having a pair of overhanging hook members 85 which are disposed in spaced relation to the respective' sides of the segmental tuft bar so as to lie adjacent the path of the wisp of Ifibre as it is being advanced to the inserting station. Adjacent thev outer sides of the respective members are a pair of fingers 87 which eX- tend from a rock shaft 89 having its bearings in brackets 90 on the support k84, the free ends of said fingers being shaped tok affordv notches 9i adjacent the respective hook members 85. llncircling the shaft is a spring 88, one end of which is secured to the shaft and the other end to a bracket 90, such spring thus tending to maintain the shaft normally in a .position with the fingers upwardly inclined and their notches 91 above theplane of the tuft bar. held in down position by a cam piece 92 on the underside ofvone arm 92 of a latch lever 'which is pivoted to the frame, as at 93, said cam piece by the actuation of the lever being movable upon and from the adjacent finger. The arm 92 is maintained yieldingly in outer active position, with the cam piece overlying` the finger, by means kof a stout retracting spring 94 attached at its respective ends lto the lever and to the frame. The other arm 95 of the latch lever extends into the path of a lugmember 96 adjustably fixed on the connecting rod 65 in such spaced relation to the arm 95 that the lug 96 impinges against and swings the arm in opposition to the spring 94, so as to remove the cam piece from the underlying finger at the moment the gap' 6l of the tuft bar, with its contained wisp of fibre, is positioned under the hook members 85'; whereupon the fingers, rising, lift the fibre from the gapl into the hoekpor- The fingers are temporarily tions andl hold it securely therein in proper;y

position for engagement by the tuft inserting mechanism. .In the downward or active stroke of the said'mechanism the fingers are depressed,I and by the retraction of the, lug` member on the rod, such fingers are subsequently locked by theV camV piece of the latch lever in the open position in readiness to engage and lift the next succeeding wisp of fibre advanced bythe fibre gathering bang (See Figs. l0, 12 and 13).

It is tov be noted that when the carrier 64V progresses nearly to -the extreme forward' position the bumper 73 is heldagainstY thel stop 74,. which arrests the further forward movement of the arm 70 andV its segments 71, including the clamping points 72, while .the vcarrier and vits nbre gathering bar conbers 85 as previously mentioned. The carrier then reverses its direction of travel, and the arm 70 with its open lclamping plates are carried thereby. When the gathering bar i is positioned with its gapunder the magazine (the upper edge `of the bar being at all times in'contact with the fibre in the magazine), the gap is supplied with the overhangingl fibre; The additional ,forward and backward movements of the bar carry the gap across the width of the lmagazine, thus insuring the' descent of an adequate quantity offibre to fill the gap, as previously explained. On the second backward4 movement the travel of the-arm 70 Yand the clamping points is arrested lby the abutment' of the bumper 78 against the stop 75, while the carrier continues a distance vsufiicient to move the gap (ilK4 of the-bar under1 they said points and to cause thel beveled end of the locking bolt 78 to pass to the opposite side of the stud 8l and lock the clamping points upon the wisp of fibre in the gap4 until it is carried to the 'clamping device beneath the tuft inserting mechanism.

Secured to the lower portion of then rear wall of the magazine frame is a bracket'in which is slidably mounted the vertical stem 97 of a compression block 98 that overhangs the fibre gatheringbar. Vithin lthe vbracket is a suitable spring 99 that 'tends to depress the block and maintain it in sliding contact with `the top of the baia rIhis block comprises a body member havingv on its lower face a central rib 100 that rests on and longitudinally of the top of the bar and two laterally depending ribs 101,'the lowerforward ends of which latter are beveled or inclined, as :113102. The position of the block is such lili) that in the final baclrward movement of the gathering bar, after the gap of the latter has been supplied with libre, such'iibre is passed beneath the ribs of the block before the clamping points are broughtinto operation, andv in consequence the tibre uniformly depressed beyond both sides of itsinedian portion by means of the lateralwalls. (See Figs. 1&1 to 17, inclusive.) i

' From the foregoing described` construction andoperation ot the relatively movable librey carrying and clamping -niembers, it will be seen that the tutt ot libre is gripped midway between its ends and that, therefore, a. uniform pull is exerted on trie wisp when it is being separated from the lcontents of 'the magazine, thus preventingdragging anddisplacement of the bres 03": the wisp and insuring a uniform collection and disposition thereof; second, that by the' provision of. means for conti' lling'the movement of the locking points ot the .relatively movable members it is possible to pass the iibre gatherer bach and' forth beneath the magazine as often as is necessary to insure the adequate filling of thelibre receiving gap; and, third, bythe agency olf` the compressor block in conjunction with the iinal rea ward impulse of the gathering bar to bring the libre under the bloei: betere the clamping points are brought into operation, the ,visp oi iibre is well pressed into the gap of the bar and the etiicient action ot the double clamping points on the ylibre is ensured. Hence there is an eiiicient retention of all the libres in the gap of the bar during the transfer of the'wisp to the inserting station,

resulting in a saving of libre and in the production of a uniformly filled brush.

As a simple and efficient means to even the ibres in the magazine, I hinge to a suitably disposed support 102 below the magazine, the lower end'of a vertical plate 108which lies adjacent the open outer vside ot the magazine and is adapted to be laterally vibrated inV amanner to press intermittently againstthe outer ends of the contained fibres. This plate is connected, by a pin and hoolr for example, to the longer arm of a horizontal lever 1011 Vwhich is fulcrumed on a -pivoted arm 105 depending from the `magazine frame, the shorter arm of the lever terminating in a toe 10G which extends into the path ofV a tappet 106` secured to the hub 'of 'the carrier, so that as the carrier approaches the end of its backward stro'lrethe tappet lmpinges against the toe and thereby slightly pulls the lever and therewith the ,plate 10S in a manner to press the latter squarely ag instthe ends of the libres contained in the niagazine. Then the carrier recedes the plate sumes its normal position in readiness ior a succeeding impact upon the return `t' the carrier. (See Figs. 10, 1l and 15.)

Referring to Figs. 13 and. 1S to 21, in-

clusive, 107 designates avertically reciprocative bar slidably fitted a suitable guideway 10S' in the supporting frame. On the outerface of this bar is a cap plate 109 bctween which and the lbar 1s supported a vertical slice comprising two spacedapart 'vertical members 110 having 'a pair of inter i'ially-grooved staple andY tutt receiving jaws at its lower end. These men'ibers are pivoted at their upper ends tothe cap plate 109 by means of screw studs lll` extending through ver ical slots 112 in the plate, and

-are thus relatively movable toward and 4from each other-,ion their pivotal supports, in a manner to permit the closing or' the opening n of lthe at the lower ends ol the members. The legso'f a spring 113, whichgis coiled on the pivot stud of one member, bear respectively against the under side of the stud 111 of the other member and against a stud v111A projecting from the former member through vslot 115 in theV cap plate'. Y Pivoted to the lower portion of the cap plate is an outwardly and upwardly inclined arm 11G having at yits lower end acaml portion 117 which bears against a movable pressure shoe'llO/ located along the edge of thev proximatev ino' 'devices' c;

patent No.' 716 9425 dated' i 7 member' 110, said arm also having at its the roll contacts with the inclined Vtace ot a vertically disposed cam bar 119 fastened to the main frame.` The contour oi the cam' face Ais such that in tiie downward stroke ot the cap plate the arm lllis swung inward, therebyA turning the cam forcibly ag*L 'rist the shoe 110 and pressing it, together .with the opposing member 11.0, toward the other member in opposition to thefforce ol the spring 113; and' that inthe upward stroke or" the/cap plate, `the arm 116 and nections, resume their normal positions. The stud of the roll 118 extends through and is guided lin an arcuate slot 12() in the upper end of an adjustable supporting arm lill which is pivoted'to the plate 109 co-axially with the cam arm. -The arm 121 is provided with an extension 122 which is adjustably secured to the plate by a screw 123 extending through a suitable arcuate slot 124 in the extension. The members 110 are resiliently connected to the bar 107 so as to have independent vertical movement thereon, by means of compression springs 125 which, being supported in a block 126 on the bar, bear upon the tops otl the respective members. The studs 111 and slots 112 determine the relative vertical movements ot' said members and bar. j

The adjacent inner edges ot the two menibers of the slide are longitudinally grooved to receive a staple driving bar 12?- which depends from a slide 128 tted in the guide wayr108 of the frame, said latter slide, togetherwith vthe bar 12.7, being relatively reciprocated vertically in the usual manner, as follows: rlhe upper end of the slitte is connected by means of a link 129 with one. arm of a rock-lever 130 which is tulci'umed at 131 on the main frame and is connected by means of a link 132 with a peripheral lug on the cam 69, previously referred to, such cam in this connection operating, in effect, as a crank arm. rIhe bar 107 is connected by means of a link 183 with the' arm 134 of a crank lever which uicrunied at 135 on the lever 130.. The other arm ot this crank lever is provided with a roll 1236 which runs in a fixed cam race 137 on the side ot the main frame, said race being ot such contour that during the oscillation ot the rocklever 130 to ellect the vertical reciprocations of the driving bar, the crank lever is actuated to impart the requisite reciprocations to the bar 107 and the slide members 110. (See Fig. 3.) V

By mechanism ofthe general construction illustrated in patent No. 578,907 aforesaid, the wire is intermittently Yted to an anvil 138 which is periodically reciprocative into and from the path ot the slide 110 in such manner that `in the initial downward movevagainst the cam bar 119, operates the cam arm to force the opposing member 110 inward in a manner to bend the legs of the conned staple toward each other and pai:- tially beneath the tutt, as seen in Fig. 19,

at or about which juncture the jaws et theA slide impinge yieldingly against the brush block7 as usual. Thereupon the bar' 127 is forced downward, by its link and lever connections with the cam 69, in a manner to impinge against the staple and drive it into the hole of the brush block. The staple in its descent doubles the wisp upon itselt' andy carries it into the hole, the tutt being therein' compressed and held by the staple, the legs whereot converge into and are iirinly and reliably held in the'brush block, as seen in Fig. 21. ln theV descent ot the staple `the spring supporting fingers 87 yield Vto the downwardrpi'essure upon the tutt as above mentioned. f K n A tutt guide casing 139 otknown construction is mounted to swing in a vertical plane toward and from the brush block in timely relation to the vertical reciprocations ofthe tutt slide, which casing is operative not only to guide the individual tufts tothe brush block, but also, by its end toes Y140,Y to.

push out ot the way ot the entering tutt the previously inserted tutt irrespective ot the direction ot movement, to the right or the lett, ofthe brushblockbelow the tutt inserting element. A vfeature of my invention resides in the provision of simple and yeil-icient mechanism for effecting the periodic operation ot the guide casing. See Figsrl, 23 and 24. As illustrated thiscasing overhangs the path of the brush block and is supported by a laterally extending roclistud 141 having itsV bearingin a bracket 142 on the main trame. Fast on this stud is a gear sector 143 in mesh with a gearV wheel. 144 loose on a stud-shatt 145 extending trom the trame, and secured to the gear is a roclnlever 146 that yis ltulcr'umed on the stud. yThe outer ends ot the respective arms of the lever are pivotally connected by links 147 -tothe lower ends ot a pair of parallel slide bars l148 supported in a vertical guidestructure 149 on the trame. Thesebars are respectively provided on their inner, taces, intermediate their ends, with oppositely-disposed notchesv 150, and therelation ofthe parts is such that when the lcasingis in vertical position, centrally of the tutt-inserting slide,..the bars 148 are in their lowermost position and the notches are directly oppositie to each other, h

lntok either otV these c as seen in Fig. 22. y p notches is adapted to be entered a laterally-y projecting stud 151 -on a pendulousbar 152 which lis hung at its'upper end from astud 153 vertically reciprocative ina guide slot- 154 formed in an upper extension guide structure 149.v 156 which is connected with a crank arm 157 (Fig. 1) tast on the pivot stud 131 ot'V the rock-lever 130, in such manner, as will presently be explained, that during theoperation et the lever` timely vertical reciproca-V tion is imparted to the bar 152.
